Arsenal

Arsenal manager Arsene Wenger looks set to pull out of a move for Rennes holding midfielder Yann M'Vila, after being less than impressed by his behaviour and temperament for France at Euro 2012.

The 22-year-old, after being substituted in the quarterfinal clash with Spain, refused to shake hands with his replacement Olivier Giroud, as well as manager Laurent Blanc.

Pulling out of a potential transfer deal for the highly-rated midfielder could come back to haunt Wenger.

A hugely experienced player at such a young age, M'Vila would bring the benefit of good midfield know-how combined with a great resale value.

And of course he'd be an excellent fit in the Gunners' system, keeping up with their passing play—he had a 83.2 pass success rate from 72 passes hit per game for Rennes last season, while he'd add a new dimension to their midfield as a great deep-lying playmaker who can actually tackle, having hit on average 7.7 accurate long balls per game and 1.1 key passes, combined with 3.1 tackles won and 2.5 interceptions made (h/t WhoScored?com).

All in all, it's a signing Arsenal will regret not making.

Aston Villa

Aston Villa, under new manager Paul Lambert, might be going places this season, but if there's one missed transfer that'll hurt them, it's not signing Grant Holt, who was linked with Villa but has recently signed a contract extension at Norwich.

The Villans lacked one major thing last season under Alex McLeish—goals.

Bringing in Lambert to rectify that problem was definitely a good idea, but Villa require more—they need a new striker.

Darren Bent was their top goalscorer in the league last season with nine goals; next best was Gabriel Agbonlahor with five.

Holt scored 15 goals in the Premier League last season and continuing at a bigger club with the same boss who has helped him perform better than he's ever done before in his career would be a recipe for success.

But alas, it's not to be and that could hurt Aston Villa's chances of finishing in the top half of the table this season.

Chelsea

Chelsea are another Premier League club who need a new striker this season.

Didier Drogba has left for Shanghai Shenhua, Fernando Torres is still inconsistent despite a great Euro 2012, Daniel Sturridge is supposedly unhappy at a lack of first-team football and Romelu Lukaku is untested.

Hulk from FC Porto and Atletico Madrid superstar Radamel Falcao seem the most likely targets at the moment, but if there's a world-class striker the Blues should be gutted to miss out on it's Gonzalo Higuain.

Higuain was the most efficient striker in La Liga last season, scoring 22 goals and making nine assists from just 1712 minutes of playing time—scoring or creating a goal for his team once every 55 minutes.

Papiss Cisse was the most efficient in the Bundesliga the season before and look at the wonders he's done for Newcastle United.

Plus Higuain, as a goal-poacher, would thrive at Chelsea with the style of teammates like Juan Mata, Eden Hazard, Frank Lampard, Raul Meireles, etc, who love making key passes.

Overall, a big opportunity missed here by Roman Abramovich.

Everton

All that's known about Luc Castaignos and Everton at the moment is that the Toffees are interested in the 19-year-old striker.

However, it doesn't seem likely they will be able to sign him, given that his club Inter Milan would prefer to sell him for £6 million, according to The Daily Mail. In any case, also according to The Daily Mail, the Goodison Park outfit will face competition from Liverpool, Tottenham Hotspur and Newcastle United—three Premier League rivals they can't compete with.

And it's a shame, because the former Feyenoord sensation would be great at Everton.

When he was given a chance in the Eredivise, Castaignos scored 15 goals having played in all of his team's 34 league games—phenomenal for an 18-year-old.

His play was reminiscent of Thierry Henry and his ability in one-on-one's showed great composure.

With Steven Pienaar behind him threading in the through balls, Castaignos would be a big success.

However, such a transfer doesn't seem likely and the Toffees will regret it.

And at Manchester City, the potential for Hazard to score and assist even more was a big possibility, especially given the strike force they have.

Not only are the likes of Sergio Aguero, Mario Balotelli and Carlos Tevez world-class finishers, they're also great link-up players, meaning a partnership with Hazard would be one of the most tantalising prospects in world football.

But of course, Chelsea will be getting all that though and quite possibly at Manchester City's expense.

Manchester United

8 of 20

Player: Eden Hazard

Club: Chelsea

Fee: £32 million

Same as Manchester City. A partnership with great link-up strikers like Wayne Rooney and Danny Welbeck would definitely have been something very special.

Shinji Kagawa is a good alternative, though not up to Hazard's standard and that's one thing the Red Devils could well regret.

Newcastle United

Newcastle United look set to sign Twente defender Douglas, but one Twente star they'll be gutted to miss out on is star striker Luuk De Jong.

The Toon have offered £10 million, but have been told by the Eredivisie club to cough up at least £15 million—something the St. James Park club are not willing to do (h/t Metro).

But with a front-three of De Jong, Papiss Cisse and Demba Ba on the cards—a combination that offered 70 goals between them last season—Newcastle would undoubtedly be a club able to cope in both the Premier League and Europa League.

If they don't change their minds and bow to Twente's demands, Newcastle could well regret rejecting the chances to sign Luuk De Jong.

Norwich City

Preparing for life without Grant Holt, Norwich City were seemingly set to turn to Nicklas Helenius, a 21-year-old striker who plays for Aalborg in Denmark.

But as it stands, Holt has signed a new three-year deal at Carrow Road, meaning Norwich are well stacked up-front with Simeon Jackson, Steve Morison and James Vaughan also on the books.

And while it's good news for the Canaries that Holt has decided to sign a new deal, it also means they could be missing out on a huge bargain.

Helenius scored 14 goals and made eight assists for Aalborg last season in 32 league games and was also a key player for the Denmark U21s, scoring four goals and making two assists in their last five matches.

A rapidly improving striker available for peanuts, Nicklas Helenius is one transfer move Norwich City will certainly regret not making.

Southampton

Southampton have already done some good business this transfer window, having signed Jay Rodriguez with Alexander Buttner soon to follow.

But one player they look set to miss out on is Matt Jarvis, who scored eight goals and made six assists last season—a very good total in a very poor team like the Wolves side relegated from the Premier League.

The Saints were linked with Jarvis back in May, but talk of a move to the St. Mary's has since died down, with Stoke City rumoured to have made a bid for the 25-year-old winger.

And missing out on Jarvis could come back to haunt Southampton, with the winger's Premier League experience and the width he provides two things lacking in the current Saints lineup.

Stoke City

Given that Lukaku is a tall, strong, athletic forward who works best out-muscling defenders and Stoke City under Tony Pulis work best with strikers in that mould, a loan move to the Britannia Stadium for the young Belgium international would seem ideal for both parties.

Unfortunately for Stoke however, they don't seem to see it that way and would prefer to sign Michael Owen according to reports.

Needless to say, this whole scenario is something the Potters will regret.

Sunderland

15 of 20

Player: Adam Johnson

Club: Manchester City

Fee: Loan

Adam Johnson could've been Sunderland-bound had it not been for one thing—his unwillingness to take a pay cut on his £80,000-a-week Manchester City wages (h/t Daily Mail).

As it stands he is unlikely to make the transition to Wearside and that's something which could be a regret for both parties.

Especially the Black Cats, who could've lined up with the tantalising prospect of Johnson on the left wing and James McClean on the right.

Two burgeoning, super-talented wingers with great pace, dribbling, crossing, trickery and finishing—and both with a big point to prove—could've seen Sunderland light up the Premier League and provide an excitement factor that would appeal to a global audience.

But thanks to the club's £60,000-a-week wage bill ceiling, that prospect is far more a dream than a reality—something Sunderland will regret big time, especially if they can't keep hold of Stephane Sessegnon.

Swansea City

If Michael Krohn-Dehli was five years younger, all of the best clubs in Europe would be after him.

As it stands, Premier League side Swansea City are keen on the 29-year-old's signature, especially after installing legendary Dane Michael Laudrup as manager.

And the player himself has said he is a big fan of the new Swansea boss.

However, Ligue 1 club Evian Thonon Gaillard are also keen on the Danish midfielder's signature, and the team's sporting director said on a move for Krohn-Dehli:

We've made an initial offer but Brondby refused to accept it.

We will do everything in our power to get an agreement and are in negotiations with the player's agent. I know that Michael wants to play for Evian so now it is up to him to show how much he wants it.

Krohn-Dehli scored goals against the Netherlands and Germany and got an assist against Portugal. A player has to have big talent to do that and Swansea will end up regretting a missed opportunity if they don't sign him pronto.

And he's an improvement on the current Tottenham centre-backs in that he's disciplined, has pace and is an excellent interceptor of the ball. Plus, unlike all their other options he's not injury-prone.

In essence, there isn't another central defender on the market with those kind of qualities, combined with the experience Vertonghen has available for Spurs.
